WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 592,764, dated November 2, 1897.

Application filed March l5, 1897.v

To @ZZ whom it may concern,.-

Be it known that I, WILLIAM L. CASADAY, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Wheel-Flows, of which the following is a specification.

My invention relates to certain improvements in wheel-plows, and is especially adapted to that class of plows in which three wheels are employed, as shown in the patent granted to me, No. 498,704, dated May 30, 1893, and comprising a landside-wheel and two adjustable furrow-wheels connected. to the frame by inclined axles.

The object of my invention is primarily to provide a plow of the type named with suitable means for converting it either into a moldboard or share plow or a disk plow, the same mechanism being used to operate either of the said plowing instruments.

A further object of my invention is to provide the frame with suitable means to admit of the adjustment of the rear supporting inclined furrow-wheel thereon when the plow is to be converted from a disk to a share and moldboard plow.

A further object of my invention is to provide the plow with novel means for adjusting both the front and rear ends of the frame to any height required to secure the required suction upon the plowshare and also to change the angle of the disk from the perpendicular.

A further object of my invention is to adjust the plow-bottom upon the standard at various .angles to secure the required suction.

A further object of my invention is to provide suitable means connected with the adjustable bracket-arm and disk j ournal-box for supporting and adjusting both an inner and an outer scraper for keeping the disk clean.

A further object of my invention is to provide-the plow with means for connecting the front and rear wheels supported upon crankaxles j ournaled in vertical sleeve-bearings to cause them to turn upon said bearings conjointly to follow the movement of the plow either in the ground or in turning, and also to make the said connection in such manner that the adjustable latch of either or bot-h Serial No. 627,582. (No model.)

the forward and rear axle-journals may set the furrow-wheels to the required angle or angles without interfering with their conjoint-operation, substantially as described.

My invention consists in certain novel constructions, arrangements, and combinations of parts hereinafter described with reference to the accompanying drawings, in which- Figure 1 is a plan view of awheel-plow embodying my invention; Fig. 2, a side elevation of the furrow side of the plow in working position, witha disk attached to the standard; Fig. 3, a rear elevation of the frame, rear furrow-wheel, and standard connections with said wheel in position to work witha disk; Fig. 4, a similar view of said parts with the rear furrow-wheel in position to work with a share-plow or plow-bottom; Fig. 5, a plan view of the rear end of the frame with the furrow-wheel and plow-bottom in the position shown in Fig. 4t; Fig. 6, a plan view cof the plow-bottom and adjacent parts of the frame with the standard in section; Fig. 7, a side elevation of the furrow side of the plow-bottom, standard, and adjacent parts of the frame and means for adjusting the standard; Fig. S, a side elevation of the landside of the parts shown in Fig. 7; Fig. 9, a rear elevation of the disk-standard and frame connections with the adjustable bracket-arm and scrapers supported adjustably thereon;

with la clevis 3, secured thereto in any preferred manner. A landside-fralne 4; is secured from the middle toward the rear end of the main frame and supports an adjustable land-wheel 5, and the forward end of the frame has an arm U at right angles to the frame, to which is secured a vertical sleeve-bearing casting 7, adjustable horizontally thereon. A vertical shaft 7b, journaled in said bearing, forms part of a crank-axle 7, upon which is supported the forward furrow-wheel 8, the horizontal adjustment of the sleeve being such that the said furrow-wheel lnay be set toward or from the frame to suit the required width of furrow in any well-known or preferred manner.

The plow-frame is provided at its rear end with a T-shaped end abutment 9, the stem 10 thereof being held between the parallel framebars 1 and secured thereto by transverse bolts 11 and 12, the cross-bar 13 of said casting projecting laterally from each side of the frame. The furrow end 13FL of the cross-bar is bent or raised above the level of the framebars l to allow the rear furrow-wheel 14- to be respectivelylowered or raised the required distance when either the plow-bottom or disk is secured to the frame. The frame is thus adapted to support the shaft-sleeve 15 of the rear furrow-wheel 1i upon the furrow side of the frame in a raised position, as shown in Fig. 3, when the disk is secured to the plowstandard, and to support said sleeve in line with the plow-frame (the bracket 15 of said sleeve bein g bolted to the landside end 13b of the rear cross-bar, as shown in Fig. 4,) when the plow-bottom is secured to the standard.

\Vhen the rear end of the plow-frame is provided with the end abutment 9, the plow may be converted from a share to a disk plow without readjusting the bearing on the axle-shaft either of the front or rear furrowwheels. This last-named adjustment can be made, however, for various purposes, among others for regulating the depth of the furrow, for changing the angle of the disk from the perpendicular, and for setting the plow-bottom to regulate the suction, and the said adjustment is readily eifected by making the upper end of the said shaft square to receive an adjustable upper collar 7 1, secured thereto by a set-screw 7f,and by providing the said crankaxle 7 with an adjustable lower collar 7 g, secured thereto by a set-screw 7 h, by which means the front furrow-wheel is adj usted vertically upon its axle. rlhe rear f urrow-wheel 1-1 is also adjusted in the same manner upon its axle,the latter being provided with a square end 14C, an adjustable upper collar l-il, provided with a set-screw Hf, and a lower collar 14g, provided with a set-screw 14h, and the upperends of the shafts both of the front and of the rear f urrow-wheels are provided with arms and toothed segment-plates for adjusting the axis of said wheels to the line of furrow, as will hereinafter appear.

The plow-standard 1G is supported to move perpendicular-ly to the frame and adjusted to the required height by parallel bars 17, segment eccentric cam 18, hand-lever19, and seetor-rack 20, as described fully in my aforesaid Letters Patent/,or by other suitable means,and the lower end of said standard is secured either io the axle-box 21 of the disk 22, as shown in Figs. 2, 9, and 10, or to the sleeve 23 of a plow-bottom, as shown in Figs. 7, 8, and 11, by bolts 1U, which maybe readily removed and the said plow-bottom and disk made interchangeable.

The plow bottom may be given the required amount of suction either by raising or lowering the forward end of the frame upon the forward furro\\f'wheel, as hereinbefore described, or by means of a wedge 24, placed between the inner wall of the sleeve 23 and the adjacent edge of the plow-staiulard, and by means of two set-screws 25, which screw through the said sleeve and bear against one edge of the standard, as shown in Figs. 7, 8, and 11 of the drawings, the wedge being held securely in the pocket formed by the opposite edge of the said standard and the side walls of the sleeve. This last-described adjustment is in many cases preferable, as it may be more easily made and as the plow-frame may then be held level when in its working position.

The axle-box 21 of the disk 22 consists in a conical sleeve 21, adapted to receive the conical journal 22 of the disk 22, secured to the latter in a suitable manner, the angle of the axis of said journal being such that the disk will be held at the required pitch or angle to the wall of the` furrow. The axlebox 21 also has a ledge 21", projecting diametrically from the rear side of the sleeve 21, provided with a side flange 21C and a slot 21d parallel thereto, upon which is adjustably secured the foot 2Gn of a bracketarm 26 by a set-screw 26", passing through said slot, the bracket-arm being thus held at a suitable distance from the back and rear side of the disk. The upper end of the arm 26 has a bearing 2Gd and set-screw 2GB, which receives the rod or shank of an inside scraper 27, which latter may thus be adjusted to closely fit the inner face or bowl of the disk, the slot 21d in the ledge of the axle -box allowing the bracket-arm to be adjusted to set the scraper 27 to bear more or less'against the disk. An outside scraper 28 has a slot-ted shank 28, which receives a set-bolt 28h, secured to the bracket-arm to clamp the said slotted shank of the scraper 28 and hold the latter to closely fit the back of the disk. The scrapers 27 and 28 are both curved to suit the curvature of the disk, as shown in Figs. 1, 2, and 9 of the drawings.

The adjustment of both the forward and rear furrow-wheels as set forth herein and in my aforesaid patent and also in my patent dated April 23, 1895, No. 538,005, is of the greatest advantage in causing said wheels to run substantially parallel with or to or from IOO IIO

the furrow in overcoming side draft and also in holding the plow from running either too far toward or away from the wall of the furrow.

The forward f urrow-wheel has its toothscgment and hinge-plate 29 secured to the hinge-plate of the tongue 30 by a tougueplate 30a, and a hand-lever 31, secured to the spindle of the axle of said "Wheel, has a latch 3l, which engages with the teeth of the segment hinge-plate 29 to hold the tongue in line with or at either an inner or an outer angle with the wall o f the furrow.

The upper squared end of the axle of the rear furrow-wheel has an arm 32 secured thereto, preferably by means of the upper collar 14d, which may be made integral therewith, and said arm 32 has anotched segment 32 thereon, which engages with a spring-dog mounted on the spindle-sleeve 15, by which means the furrow-wheel is caused to run in line with the frame or at the required angle thereto and at the saine time permitsit to lock and unlock when turning to the left in a right-hand plow, the said parts being so arranged that the furrow-wheel will not turn when the plowis turned to the right, but will form a pivot for said plow.

l/Vhen the plow is turned to the right or left, the rear furrow-wheel is caused to turn with the forward furrow-wheel positively by means of a coupling-rod 33, connecting an extension-arm 3,2b on the arm 32 with the lever 3l of the forward caster-wheel axle and tongue-plate in a diagonal line from the inside of the forward furrow-wheel to outside of the rear furrow-wheel, the said couplingrod being also bowed at its rear end to clear the plow-disk and by means of its reverse connection to the axles of said wheels to hold the said axles radially to the circle described by the said wheels in turning. The forward end of the coupling-rod 33 is slotted to receive a pin 31h, carried by a bracket-arm 3le upon the lever 3 1, and thus allow the said lever to be adjusted upon the segment-plate of the tongue-hinge without changing its connection with the arm 32 of the rear furrowwheel. The coupling-rod 33 is preferably made of two plates secured together by thimbled bolts placed between the plates at suitable distances thereon,thus securing strength, lightness, and rigidity.

In all of its adjustments the plow herein shown may be readilyset and adapted to receive either a disk plow or a share-plow, the relative positions and connections of said interchangeable parts upon the frame being such that the plow will work equally well with either connection and without employing additional or supplemental parts.

The mode of setting and adjusting the plow-bottom upon the standard to secure suction does not interfere with the substitution of a disk journal-box for the plow-bottom sleeve, and the mode ofl supporting, connecting, and adjusting the disk scrapers is strong and effective, enabling both the outer and inner surfaces of the disk to be kept perfectly clean.

The simple means for supporting and regulating the height of the plow-frame and for adjusting the furrow-wheels thereon provide an implement which may be readily adj usted and operated in the field by any one of ordinary skill, the parts when thus adjusted being securely. held and not liable to become displaced. Besides this the furrow-wheels are connected by positive means which enable the plow to be easily turned at the end of the furrow.

I claim as my invention and desire to secure by Letters Patentl. In a wheel-plow, the combination with the frame having a longitudinal beam, a landside-frame, a landside-wheel, a plow-standard adapted to receive interchangeably a plowshare and a disk, a forward furrow-wheel supported upon an arm projecting laterally from the frame, a rear abutment secured to the beam, an adjustable bearing-block adapted to be secured to the said abutment, arear furrow-wheel and an axle carried upon said latl erally-adj ustable bearin g-block,substantiall y as described.

In a wheel-plow, the combination with a frame carrying the plow-standard of the landwheel of laterally-projecting` arms, respectively at the front and rear ends of the frame, j ournal-bearings thereon at right angles to the frame, forward and rear furrow-wheels each supported upon crank-axles having vertical shafts supported and adjusted in said'bearings, the collars and set-bolts fitted upon said shafts above and below the bearings to hold the spindles in their adjusted positions, substantially as described.

3. In a wheel-plow,the combination with the frame of the standard adapted to be adjusted vertically thereon, a plow-bottom having a socket adapted to fit said standard, transverse bolts fitted in said socket to bear against the side of the standard, a wedge-block adjustable vertically in the walls of the sleeve and standard and set-screws fitted upon said sleeve to be ad j usted against said standard opposite the wedge-block, substantially as described.

4. In a disk plow, the combination with the frame of the supportingwheels, the vertically-adjustable standard, the disk journalbox having a ledge upon one side thereof, a bracket-arm having laterally-adj ustable footing upon said ledge, an inner scraper adjustable radially upon the end of said arm, and adjustable toward or from the face of the disk by means of the adjust-able bracket-footing, substantially as described.

5. In a wheel-plow, the combination with a IOO IIO

frame carrying the plow, a land-wheel, a rear r4 l A 592,764

meeting the tongue and spindle of the forward furrow-Wheel and a Coupling-rod pivotaily connected to the lever of the rear axle having a slot at its forward end and connected adjustably to the latch-lever to admit of the adjustment of the latter, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name iu the presence of two subscribing Witnesses.
